The Gotha G.IV was a heavy bomber used by the Imperial German Air Service during World War I. Designed for long-range service, the G IV series was used principally as night bombers entered service in August 1917.

The Gotha G.IV pilot seat was offset to port with the fuel tanks immediately behind. This blocked the connecting walkway that previously on earlier machines allowed crew members to move between the three gun stations. All bombs were carried externally in this model. The Gotha included an important innovation in the form of a "gun tunnel" whereby the underside of the rear fuselage was arched, early versions allowing placement of a rearward-facing machine gun protecting from attack from below, removing the blind spot. Later versions expanded the tunnel to remove the lower gun, providing a slot in the upper fuselage that allowed the rear gunner to remain stationary.
